On the other hand, even if the thickness exceeds 200 μm, the equivalent effect cannot be obtained, which is disadvantageous in terms of manufacturing cost.
[0024]
Further, the outermost layer 12, the intermediate layer 13, and the innermost layer 14 are bonded and laminated. As an adhesion method between the layers, a dry lamination method is preferably employed.
[0025]

The blending amount is preferably 0.01 to 15% by weight, and if it exceeds 15% by weight, there is a high risk of causing hair damage. The pH of the first agent is adjusted to pH 6.0 to 10.0, preferably 7.5 to 9.5.
[0031]
In the case of a permanent wave agent, the first agent contains a reducing agent, an alkali agent, and the like, and the second agent contains an oxidizing agent and the like.
[0032]

[0043]
The second component of the permanent wave agent was 5.7% by weight of hydrogen peroxide (35%), 0.05% by weight of xanthan gum, and phosphoric acid at a pH of 3.5, with the remainder of purified water blended. Things are used.
[0044]
Next, the operation of the hair cosmetic container configured as described above will be described.
Now, when the hair cosmetic is stored in a state of being stored in the hair cosmetic storage container 11 of the embodiment, the components in the hair cosmetic gradually penetrate into the innermost layer 14 from the inside and try to leak out to the outside. . However, since the components in the hair cosmetic cannot penetrate into the surface of the hair cosmetic storage container 11, there is no fear that the components in the hair cosmetic will decrease during storage.
[0045]
As described above, according to this embodiment, the following effects are exhibited.
The hair cosmetic container 11 of the embodiment is excellent in barrier properties, but has a saturated polyethylene resin layer deposited on the outer surface of the intermediate layer 13 that is inferior in water resistance with an inorganic material having excellent barrier properties and water resistance on the inner surface. Although it is inferior in barrier property, it is formed by the material which joined the polyolefin resin layer 14a excellent in water resistance and chemical resistance. Accordingly, it is possible to compensate for each other's drawbacks and obtain a resin container having excellent barrier properties, water resistance, and chemical resistance.
[0046]
-Hair cosmetic container 11 of embodiment is formed with the material which has transparency. For this reason, the remaining amount of the contents can be easily confirmed, and what the stored contents are can be easily confirmed just by looking from the outside. That is, in the case of a two-component permanent wave agent, the first agent and the second agent are not mistaken.
[0047]
The hair cosmetic container 11 according to the embodiment is formed of a material that is clean with respect to the environment. For this reason, dioxin etc. are not generated at the time of incineration, and the incineration residue is extremely small.
[0048]
In the hair cosmetic container 11 according to the embodiment, the innermost layer 14 is formed of a polyolefin resin layer 13b having excellent water resistance and chemical resistance. For this reason, even when a second agent such as a permanent wave agent and an oxidative hair dye is stored, there is almost no possibility that bromate, hydrogen peroxide, etc., which are oxidizing agents, are decomposed with time.
[0049]
Even if, for example, hydrogen peroxide in the contents is decomposed and oxygen is generated, the internal pressure in the container body suddenly rises, and the container body can be thin even if the pressure may concentrate on a specific location. Since the sheet material is formed of a flexible laminated sheet material, the sheet material can be flexed softly to disperse the pressure and prevent the container body from being ruptured. Therefore, the storage stability of the second agent such as a permanent wave agent and an oxidative hair dye can be improved.
It can also be used as a refill container.
[0050]
By the way, when using a first agent such as a permanent wave agent or an oxidative hair dye that contains highly volatile ammonia as an alkaline agent as a hair cosmetic, a conventional ethylene-vinyl alcohol copolymer or polyamide system is used. It was difficult to completely prevent the permeation of ammonia with only a barrier layer such as a biaxially stretched resin.
[0051]
Therefore, attempts have been made to prevent the permeation of ammonia by using an aluminum film instead of an ethylene-vinyl alcohol copolymer or a polyamide-based biaxially stretched resin, but the incinerator is damaged during incineration. In addition to environmental problems, the visibility inside the container body is poor, and the remaining amount of contents cannot be confirmed.
[0052]
However, in the hair cosmetic container according to the embodiment, the barrier layer is formed by two layers of the saturated polyethylene resin layer on which the inorganic substance is deposited and the ethylene-vinyl alcohol copolymer or the polyamide biaxially stretched resin layer. Even when a hair cosmetic containing highly functional ammonia as an alkaline agent is accommodated, the permeation of ammonia can be sufficiently prevented, and the remaining amount of the contents can be easily confirmed. Therefore, the storage stability of a hair cosmetic containing an alkaline agent can be improved.
[0053]
In addition, this embodiment can also be changed and embodied as follows.
-It comprises with a pair of 1st packaging bags and 2nd packaging bags which connected the hair cosmetics storage container 11 of embodiment in the center. When comprised in this way, the 1st agent and 2nd agent of a two-component hair cosmetics can each be accommodated.
[0054]
The hair cosmetic container 11 according to the embodiment is formed as a standing pouch container having self-supporting properties. When comprised in this way, it can be used also as a refill container or a main body container.
[0055]
The layer configuration of the hair dye storage container 11 of the embodiment is, for example, in the order of the outermost layer to the innermost layer, for example, inorganic vapor deposited PET layer / EVOH / O—Ny / polyolefin-based resin layer, inorganic vapor deposited PET layer / O—Ny / EVOH / polyolefin resin layer, inorganic vapor deposited PET layer / O-Ny / O-PP (stretched polypropylene) / polyolefin resin layer, inorganic vapor deposited PET layer / EVOH / O-PP / polyolefin resin layer, and the like. When comprised in this way, barrier property can be improved more.
[0056]
Examples that further embody the above-described embodiment will be described below.
In Example 1 and Comparative Examples 1 and 2, the first container and the second container are formed separately, and each is made of a resin material made of the materials shown in Table 1 (the left end indicates the outer layer side and the right end indicates the inner layer side). A first container and a second container were formed. Then, the first agent and the second agent for the permanent wave agent were respectively stored in the first container and the second container and stored in a 45 ° C. constant temperature bath for 3 months, and then the wave effect on the hair bundle was evaluated. The results are shown in Table 1.
[0057]
The first container used had an outermost layer thickness of approximately 12 μm, an intermediate layer thickness of approximately 15 μm, and an innermost layer thickness of approximately 110 μm.
[0058]
The permanent wave agent (a) was used as the permanent wave agent.
[0059]
The wave effect is evaluated as wave efficiency by the Kilby method. When the wave efficiency is almost the same as the wave efficiency when using the permanent wave agent before storage, the wave effect is slightly different. When the efficiency is obtained, Δ is indicated, and when the wave efficiency is considerably different, × is indicated.
[Table 1]

[0060]
From the results in Table 1, it was shown that the wave efficiency was good in Example 1. That is, in the case of the laminated container in which the PET-SiO _X layer and the O-Ny layer are arranged in the outermost layer and the intermediate layer, respectively, it was shown that the storage stability of the first agent was good.
[0061]
In Comparative Example 1, it was shown that the wave efficiency was slightly poor. That is, it was shown that the storage stability of the first agent was poor when the first container was formed by disposing a PET resin layer not subjected to silica vapor deposition as the outermost layer.
[0062]
In Comparative Example 2, it was shown that the wave efficiency was poor. That is, when the first container was formed with a layer configuration not including the biaxially stretched nylon layer, it was shown that the storage stability of the first agent was poor.
[0063]
Next, the technical idea that can be grasped from the embodiment will be described below.
The hair cosmetic container according to any one of claims 1 to 4, wherein the hair cosmetic container has transparency. When comprised in this way, while being able to confirm the remaining amount of a content easily, what is the stored content can be easily confirmed only by seeing from the outside.
[0064]
